ABSTRACT:
The apparatus includes an endless nylon rope trained over two distally mounted sheaves which define paths spanning either side of the distally mounted sheaves and means for the continuous application of herbicide to the endless rope. The means for applying herbicide to the rope includes an immersion basin in which portions of the rope are continually pulled through a shallow level of herbicide. This is accomplished by training the endless rope onto a drive drum having at least one revolution of rope wherein the bottom of the drum is at a level below the level of the herbicide and an idler drum driven by the driven rope which again has at least one revolution or loop of wetted rope around it and which is submerged in the herbicide within the immersion basin. The distally mounted sheaves are journalled at the end of a boom which extends transversely of a frame work installed onto a tractor and which has height adjustment means allowing the boom and the endless rope trained thereon to be raised or lowered so that the wetted rope wipingly engages the weeds but does not engage the crop. Normally, the weeds grow higher than do the desirable plants, at least in the early stages.
